+title: GNU Guix and GuixSD 0.13.0 released

+We are pleased to announce the new release of GNU Guix and GuixSD,
+version 0.13.0!
+
+The release comes with
+[GuixSD USB installation images](https://www.gnu.org/software/guix/manual/html_node/System-Installation.html),
+a
+[virtual machine image of GuixSD](https://www.gnu.org/software/guix/manual/html_node/Running-GuixSD-in-a-VM.html),
+and with tarballs to install the package manager on top of your
+GNU/Linux distro, either
+[from source](https://www.gnu.org/software/guix/manual/html_node/Requirements.html)
+or
+[from binaries](https://www.gnu.org/software/guix/manual/html_node/Binary-Installation.html).
+
+It’s been 5 months since the previous release, during which 83 people
+contribute code and packages.  The highlights include:
+
+  - Guix now supports aarch64 (64-bit ARM processors).  This release
+    does not include a binary installation tarball though, and our build
+    farm does not provide aarch64
+    [substitutes](https://www.gnu.org/software/guix/manual/html_node/Substitutes.html)
+    yet.  We are looking for aarch64 hardware to address this.  Please
+    [get in touch with us](https://www.gnu.org/software/guix/donate/) if
+    you can help!
+  - Likewise, this release no longer includes a mips64el tarball, though
+    Guix still supports that platform.  We do not know whether we will
+    continue to support mips64el in the long run; if you’d like to weigh
+    in, please email us on `guix-devel@gnu.org`!
+  - The GuixSD installation image now supports UEFI.  GuixSD can also be
+    installed on Btrfs now.
+  - GuixSD has support to run system services (daemons) in isolated
+    containers as a way to mitigate the arm that can be done by
+    vulnerabilities in those daemons.  See
+    [this article from April](https://www.gnu.org/software/guix/news/running-system-services-in-containers.html).
+  - A new
+    [`guix pack`](https://www.gnu.org/software/guix/manual/html_node/Invoking-guix-pack.html)
+    command to create standalone binary bundles is available.  We
+    [presented it in March](https://www.gnu.org/software/guix/news/creating-bundles-with-guix-pack.html).
+  - Guix now runs on the
+    [brand-new 2.2 series of GNU Guile](https://www.gnu.org/software/guile/news/gnu-guile-220-released.html).
+    The transition led to hiccups that we have been addressing, in particular
+    [for users of `guix pull`](https://lists.gnu.org/archive/html/guix-devel/2017-05/msg00123.html).
+    Among other things though, the
+    [noticeable performance improvement](https://lists.gnu.org/archive/html/guix-devel/2017-04/msg00427.html)
+    that comes for free is welcome!
+  - Many reproducibility issues found in packages have been
+    addressed—more on that in a future post.
+  - 840 new packages, leading to
+    [a total of 5,400+](https://www.gnu.org/software/guix/packages/),
+    and many updates, including glibc 2.25, Linux-libre 4.11, and GCC 7.
+  - New
+    [system services](https://www.gnu.org/software/guix/manual/html_node/Services.html)
+    for Redis, Exim, Open vSwitch, and more.  The interface of existing
+    services, notably that of the
+    [NGINX service](https://www.gnu.org/software/guix/manual/html_node/Web-Services.html),
+    has been greatly improved.
+
+See the release announcement for details.
+
+#### About GNU Guix
+
+[GNU Guix](https://www.gnu.org/software/guix) is a transactional package
+manager for the GNU system.  The Guix System Distribution or GuixSD is
+an advanced distribution of the GNU system that relies on GNU Guix and
+[respects the user's
+freedom](https://www.gnu.org/distros/free-system-distribution-guidelines.html).
+
+In addition to standard package management features, Guix supports
+transactional upgrades and roll-backs, unprivileged package management,
+per-user profiles, and garbage collection.  Guix uses low-level
+mechanisms from the Nix package manager, except that packages are
+defined as native [Guile](https://www.gnu.org/software/guile) modules,
+using extensions to the [Scheme](http://schemers.org) language.  GuixSD
+offers a declarative approach to operating system configuration
+management, and is highly customizable and hackable.
+
+GuixSD can be used on an i686 or x86_64 machine.  It is also possible to
+use Guix on top of an already installed GNU/Linux system, including on
+mips64el, armv7, and aarch64.
